Abstract :
The design of a tunable continuous-time active-RC leapfrog filter whose precise response is controlled by means of a novel successive approximation tuning technique independent of tight circuit components matching. An RLC prototype ladder is described, together with the tunable active-RC leapfrog architecture. Experimental results are presented
